ATTACHMENT FOR TBACTORS.

Original application led December 8, 19M, Serial No. 754,873. Dividedand this application med me), 7, 1927. Serial No. 178,467.

This invention relates to an attachment for tractors, and moreparticularly to a continuing application of my prior application forpatent, filed December 6, 1924, Serial #754,373, and the primar objectof this 1nvention is the provision o a novel construction of attachmentwhereby various t es of machinery or other apparatus may e supportedfrom the tractor in a very economical, inexpensive manner. c

An object of the invention is the provision of an attachment that issecured to and solely supported from the radiator of the tractor in sucha novel manner that the attaching and detaching of the structure fromthe tractor 1s greatly facilitated. I

Another object of the invention is the provision of clamps or bracketsthat are designed in a novel manner to interlock or interit with ceitainparts of the radiator as now constructed so that when placed they willnot only rigidly and substantially support the other parts connectedhereto but will coact 1n a manner to greatly strengthen the usual Harigeconnections of the component parts of the radiator.

Another object of invention is the design of clamp structures that passentirely around and effectively embrace the upper and lower portions ofthe radiator in such a novel manner that the table may be eectivelysecured to one clamp structure for swinging movement, and the usualbrace structures positioned above the table for ready accessibility oradjustment.

Besides the above, my invention is distinguished in the novelconstruction and design of each plate so that the saine Will effectivelyengage the flanges and the exposed bolt heads and nuts so that shiftingof the plates is positively prevented when the tie rods are properlytightened.

Another feature of my invention is the novel manner of designing andarranging the parts so that the clamp structures only contact with andengage the most substantial part of tle radiator, which is the sideportions thereo The arrangement of the brace structures above the tableand the novel design thereof which facilitates adjustments is anotherimportant feature of my invention, as the conu struction enables thetable to be readily raised and lowered and when in either of its twopositions effectively held therein.

With these and other objects in view, my invention will be betterunderstood from u description of the accompanying drawings in whichFigure 1 is a side elevation of the attachment shownapplied to a tractorradiator;

Figure 2 is a top dplan view;

Figure 3 is a si e elevation showin the table raised to facilitatecranking o the motor or travel of the tractor over the ground Fivure 4is a cross sectional view of one of the c amp plates;

Figure 5 is a horizontal sectional view through one of the clamp platesand its associated parts;

Flgure 6 is a perspective View of one of the lower clamp plates;

Figure 7 is a view similar to Figure 6, looking at the opposite sidesthereof;

Figure 8 is a perspective view of one of the upper clamp plates;

Figure 9 is a View similar to Figure 8, looking at the opposite sides ofthe plates;

Figures 10 and 11 are fragmentary views of a modled form of brace thatmay be used with my invention.

Again referring to the drawings illustrating one of the manyconstructions of my invention, the numeral 1 designates a table forsupporting any suitable form of machinery or apparatus that it isadvisable to drive from the usual drive pulley carried by the tractor 2,and 1n fact may be used as a work table. This table includes the sidebars 3 that extend toward the radiator 4 of the tractor to be swinginglymounted on the pivot bolt 26 that forms one of the elements of the lowerc lampstructure 6 that functions in conjunction with the upper clampstructure 7 to effectively and rigidly support the table solely from theradiator 4 in a manner to allow the table to assume a horizontal oerative osition or to be swung vertically to a low rea y access to thecrank of the tractor or to facilitate the travel of the tractor. Theseclam structures not only effectively support t e table solely from theradiator but engage the c011- st1tuent parts of the radiator,y in amanner to greatly reinforce the connections therebetween in a manner nowto be described.

rlhe upper clamp structure consists of the pair of plates 8, each havinga groove 9 for receiving and embracing the upper companion flan es 10 ofthe radiator structure 4. As 1s usua in the construction of tractorradiators now on the market, the bolt head 11 and nuts 12 are arrangedin exposed projectmg ositions, and for the purpose of bringing a out amore effective engagement between the plates and the radiator, the plate1s provlded with notches 13 for receiving the bolt heads and lugs 14 forengagement between the nuts, With the shoulder 15 arranged 1n abuttlngrelation with the rear edges lof the flanges the-plates are effective]held against dlsplacement when the tie ro. s 16 are brought into tightclamping engagement with the plates.

Particular attention is called to the fact that the clamp constructionis such that the binding en agement of the lates 1s against the most sustantial part of t e radiator, that is to say, the side walls thereof,the tie rods 16 being so ositioned as to be arranged 1n spaced para elrelation with the front and rear of the radiator, thereby preventlng anf interference with the passage of air throng the core of the radiatoror subjecting the core of the radiator to pressure or strain. The plates8 are further provided with threaded studs. 17 for a urpose hereinafterdescribed.

The lower clgmp structure includes plates 18 of a construction similarto the upper plates so as to provide notches 19 for receiving the boltheads of the flanges of the radiator arranged in the groove 20, similarlugs 21 belng rovided to co-operate with the nuts of the anges. Thelower plates are also provided with shoulders 22 in abutting relationw1th the associated flanges of the radiator, and thus the lower platesare eiectlvely held against displacement upon tightening of the tie rods23. The lower plates are provided with bosses or projections 24threaded, as indicated at 25, to receive the pivot bolts 26 thatpivotally connect the side bars 3 to the clamp plates.

At this point I wish to call attention to the fact that the plates areclamped to the four corner portions of the radiator as units and theother parts of the attachment are detachably connected thereto, therebyenabling me to attach various other structures to the clamps when foundadvisable. This novel construction of clamp is such that the effectiveengagement with the radiator is not disturbed in any manner in themovements or adjustment of the other parts of the attachment.

It will be noted that the braces 27 are positioned entirely above thetable where they are readily accessible for adjustments or detachmentfrom the brackets, thereby eliminating the necessity of getting underthe table and disconnecting plarts when it is necessary to raise orlower t e table. The braces 27 are pivo'tally connected to the 'sidebars, as

indicated at 28, and their upper ends are pro. vided with holes 29 forreceiving the heretofore mentioned studs 17, nuts 30 mounted on thestuds effectively holdin the braces in engagement with the associateclamp plates. Each brace 27 is further provided with a notch 31 sodisposed as to engage the stud when the table is thrown into itsvertical angular position, as shown in Figure 3, and thus the upperclamp plates are capable of performing the dual function of supportingthe table in a horizontal position or in a vertical inclined position.

It may be advisable to so design each brace that the same may beautomatically detached from the stud in the upper Swingin movement ofthe table, and one manner of accomplishing this desired result would beto pro vide an inclined slot 32 that will automatically receive the stud17 in the downward swinging movement of the table and will automaticallydisengage from the stud in the upper swinging movement of the table, and`for the purpose of preventing accidental disengagement a wing nut 32may be utilized, as shown in Figure 10.

In Fiofure 11, I have shown the brace plate provided with a series ofnotches 33 for accommodating a plurality of adjustments of the table toassure the proper horizontal positioning thereof or the properpositioning of the machinery carried thereby with relation to the driveulley of the tractor.

In conclu ing, I wish to lay considerable stress upon the simplicit ofconstruction and the substantial manner 1n which each part is connectedand associated so that not only will the table be effectively andlsolely supported from the four corners of the radiator but the radiatoritself will be effectively reinforced against strain. Alladjustableparts are sitioned above the table to facilitate adjustments and thevarious clamp structures are effectively clamped to the radiatoras'units so that the clamping action thereof will not be affectedorinterfered with in the usual movements or adjustments of the otherparts of the attachment which are adj ustably connected to the bracketstructure through the use of independent connections.

Of course, it is to be understood that the brackets, table and bracesmay be designed and constructed in various other manners thanillustrated and associated with each other in other manners thanillustrated and, therefore, I do not desire to be limited in any mannerexcept as set forth in the following claims.
